This study examined correlations between U-Service for U-City and assessment indicators for urban competitiveness. The results of this study show that U-Service is used as a means of strengthening urban competitiveness in six types of cities, despite the differences in degree of contribution. The proper use of U-Service in Safety & Health City and Vitality (Economy) City has significantly contributed to strengthening the competitiveness of such cities. Of the assessment items for urban competitiveness, common items and Culture City type show that U-Service has not contributed much to strengthening urban competitiveness. The analysis shows that because common items are part of the assessment items for urban policies, these items are not suitable to the character of a U-City that implements U-Service through intelligent physical facilities. On the other hand, U-Service related to the Culture City type is relatively less developed. This study found out that U-Service could be used to reinforce urban competitiveness.

In this study, changes in commercial areas in Yeongdo-gu urban regeneration region were analyzed in terms of regional revitalization. Urban decline can accelerate the decline of downtown commercial functions, and revitalization of stagnant areas can be evaluated as enhancing the vitality of commercial areas. To reach this objective, dynamic changes in the commercial area in urban regeneration region were confirmed through store density, industry diversity, and restaurant/cafe ratio. As a result of the study, it was found that the store density and industry diversity showed an increasing trend in Yeong-do urban regeneration region. Although it is difficult to find a substantial difference in the ratio of restaurant/cafe, it seems that Yeongseon 2-dong has undergone a relatively large commercial change. This research is significant in that it quantitatively evaluated and analyzed commercial changes in Yeongdo-gu urban regeneration region.

Urban nature plays an important role not only in the improvement of the physical environment but also from the perspective of psychological and social function. In particular, schoolyards as well as the green spaces near school surroundings function as a primary space for urban children to experience nature in Korea, as they spend most of their time at school. In this study, the status of urban green spaces near school surroundings was examined. For the analysis, 185 elementary schools in Seoul were selected and the green spaces within a radius of 300m(defined as 'school zone' in this study) were analyzed using the Rapid Eye multispectral satellite image data. The mean green space ratio of school zone accounts to about 21% with a high variation from 74% to 0.7% and more than half of the school zone have a green space ratio of less than 20%. Schools with a high green space ratio in their school zone are mostly located near urban forests, so forest areas particularly contribute to increase the green space ratio. Furthermore, forest vegetation shows relatively higher vitality than other green spaces located in urbanized areas. In contrast, schools with a low green space ratio in their school zone are mostly situated in high-density residential areas and the green spaces show relatively low vegetation vitality. Except for the urban forest, the majority of urban green spaces in urbanized areas are landscape green facilities in apartment districts. The other types of urban open spaces such as environmentally shaped schoolyards or street parks account only for a very small proportion of school surroundings. Therefore, it is needed to establish countermeasures in the context of urban planning; e.g. to promote the school forest projects preferentially by selecting schools with a extremely low green space ratio in their school zone, to foster roof greening in near surroundings, and to connect schoolyards organically with nearby apartment landscape green facilities as an easily accessible urban open space.

The vegetation activity of the Korean peninsula has been monitored temporal variations through a satellite remote sensing and the vegetation index was used to set up the vegetation data map of Korea. The AVHRR data sent by the NOAA-14 satellite was collected for 8 months between April and November, 1997 to calculate the normalized difference vegetation index(NDVI) which was combined the MVC(Maximum Value Composite). Then this NDVI composite map was prepared to review the temporal variations in the vegetation activity. The NDVI has been subject to the unsupervised classification for the growing season between May and October. And the vegetation type is divided into five classes ; urban, bare soil, grass, farming land, deciduous forest and coniferous forest. The unsupervised classificaion of vegetation distribution in the Korean Peninsula shows that the urban and bare soil take 4.14% of total national area, grass 4.49%, farming land 27.54%, deciduous forest 25.61% and coniferous forest 38.22%.

A number of cities have been constantly decreasing their residents by the low quality of life and environment. A creative industry is being noticed for not only securing the competitiveness of the city but also increasing the number of population. Thus, the urban structure for inducing creative industry population becomes to major issue to the most of local governments. This study aims to suggest the relationships between urban structure and creative industry population based on different urban sizes. To measure the population of creative industry, this study used the 'National Business Survey' by the National Statistical Office, which classified the statistical data of industrial places on a basis of city, district, and borough. Based on the results of expert questionnaire surveys, it conducted an analysis on the importance of urban structure and drew some critical factors that have an important effect on attracting the population of creative industry. The relationships between creative industry population and urban structure evaluated by multiple regression analysis. This study found out that the cultural factors like cultural space or culture events were drawn as very significant factors that have a positive effect on the population of creative industry population. It is judged that the creation of culture environment, which can enrich the creative industry, is needed to strengthen the competitiveness of the cities.

Areas with negative images in cities can degrade the image of the city as a whole and slow the city's efforts to improve its image. The identification of such areas and the development of a city contour that charts the images of various areas in advance can help urban planners establish relevant strategies to ameliorate detrimental images of the city. This study intends to draw a contour of Seongnam City according to citizen's cognition levels of and preference for city area images and aim to shift the strategy of urban image planning from being results-oriented to being process-oriented. The results of this study are as follows: First, an analysis of the level of cognition of and preferences for Seongnam City's landmarks shows that the degree of cognition varies in different areas, whereas that of preferences remains similar; Second, the cognition and preference contour makes it easy to assess and diagnose city images; Third, the image management map, which merges the cognition contour with the preference contour, divides the city into four different areas. In order to manage city images, it follows that those areas with a high degree of cognition but low preference need to be classified and dealt with first. Further, this study shows that those areas with high cognition are the most populated and visited. Areas with high preference can become a strong candidate for being a landscape control point of a city, which adds to the usefulness of this study. The contour of Seongnam will contribute to networking sightseeing areas for visitors centered upon those places of high preference. It would appear that this type of networking will inspire a better image for the city.

Recently increasing the supply of housing policy has not been able to reflect social phenomena as like decreasing birth rate, aging of the population and increasing 1 or 2 person households. This study analyze the housing demand in the city with the point of population growth rate and economic character changes. Growing cities have positive population growth rate and economic character, but shrinking cities have the opposite. By comparing housing demand of growing cities and shrinking cities, we want to find out housing policy implications. In this study, results suggest that the peak age of housing demand of shrinking cities is the late 60's. But the growing cities's age peak is the mid-80's. But further analysis of the economic variables and 1 or 2 person old and young household dummies, the result is that the peak age of housing demand is reduced. These results suggest that housing demand should be differentiated the cities's population structure and economic characteristics of the household. In short, housing demand will vary depending on the condition of individual cities.
